New powerful and reliable 1.8+HP .18 Race Nitro RC Engine for MOST 1/10 Nitro Trucks, Cars, Buggies, Truggies, Boats, and more.  It has the same mounting bolt pattern as most other standard 1/10 nitro engines, and has the most universal output shaft on the market to fit most clutches and bells.  It has the side exhaust that works with many 1/10 vehicle stock exhaust systems (ask if you are not sure.)

Carburetor is REVERSIBLE.

NOTE: PLEASE REVIEW PICTURES TO SEE IF THIS ENGINE IS COMPATIBLE WITH YOUR VEHICLE BEFORE PURCHASING. THIS IS A UNIVERSAL ENGINE THAT IS NOT AN EXACT REPLACEMENT FOR MOST ENGINES OR BRANDS. Most vehicles may need at least one or two small hardware pieces such as a screw or washer in order to attach your clutch and flywheel assembly properly. If you are not sure if it will fit your vehicle, please ask and I will be glad to help.  Please study the pictures and read the entire description before purchasing.

Great upgrade or replacement for many Traxxas, HPI, Losi, Team Associated and many other .12 - .18+ engines.  The Traxxas 2.5/3.3 EZ-Start or Pull Start will bolt on IF you slightly enlarge the mounting holes on the EZ-Start unit, and the Clutch Assembly is a direct bolt on, BUT it has a side exhaust as shown, which is compatible with the TRX .15 and many other 1/10 side exhausts.  It is such a close fit that the EZ-Start backplate may fit without modification, but I enlarged the holes on mine by less than .1mm and it fit perfectly.  It will require using the Traxxas one-way bearing, which is a perfect fit on this shaft.  Fits many roto-start and other backplates as well.  HAS SIDE EXHAUST, NOT REAR.

Features:
• ABC construction, Aluminum piston with Brass liner that's Chrome plated
• Dual ball bearing-supported crankshaft
• 12mm SG Crankshaft
• Large anodized head with cooling fins 
• Pull starter pre-installed
- Side exhaust (same as TRX .15, OS .18 CVR and most other side exhaust nitro engines for 1/10 vehicles)
